The ______ are used to change the vapor to a liquid and the liquid form back into a vapor in the refrigeration cycle.

The components responsible for changing the vapor to a liquid and vice versa in the refrigeration cycle are the condenser and evaporator.

In the refrigeration cycle, the condenser is the component where the refrigerant, initially in its vapor state after being compressed, releases heat to the surrounding environment and condenses into a liquid. This process involves the transfer of heat out of the refrigerant, allowing it to change from a vapor to a liquid, which is crucial for efficient heat exchange.

Conversely, the evaporator is where the refrigerant absorbs heat from the space or substance it is cooling. In the evaporator, the refrigerant, which is now a liquid, evaporates by absorbing heat and transitions back into vapor. This absorption of heat is what cools the surrounding air or water.

Understanding the roles of these components is essential for grasping how the refrigeration cycle operates to maintain desired temperatures in various applications.
